TWIN FLOW FLUEING
For standard horizontal flueing the Twin Flow is supplied with a flue kit including:
2 x wall terminal 600mm long, concentric, 80/125.
2 x white gasket (internal)
2 x black gasket (external)
1 x straight F/F adapter
2 x 90 bend M/F
The flue connection on the top of the water heater is a male connection. When
flueing directly through the wall behind the Twin Flow the water heater must have a
straight Female/Female adapter, then a male/female 90 degree bend and then the
wall terminal. This should tip slightly down to the outside to prevent rain ingress.
The boiler has a female connection on the top of the unit. The boiler requires a
male/female 90 degree bend and the wall terminal. This should tip slightly back to
the boiler to prevent a drip hazard outside the building.
Other flue combinations are available from Rinnai. The appliance flues can
terminate horizontally or vertically and can extend long distances. The water heater
can flue 15m less 2m per bend to a maximum of 4 bends, and a maximum height of
9m. The boiler can flue 24m less 3m per 90 degree bend or 1m per 45 degree bend
with no maximum height or number of bends.
A full programme of parts are available from Rinnai UK.
